If you are working in Java environment, you could use the Java class 'Random' for random number support. (http://java.sun.com/javase/6/docs/api/java/util/Random.html). Supposing your input XML is (this is just an example for illustration. your real XML could be different.): <images> <image val="a.jpg" /> <image val="b.jpg" /> <image val="c.jpg" /> <image val="d.jpg" /> <image val="e.jpg" /> <image val="f.jpg" /> </images> The stylesheet could be: <?xml version="1.0" encoding="UTF-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java" version="1.0"> <xsl:output method="html" /> <xsl:template match="/"> <xsl:variable name="max" select="count(images/image)" /> <xsl:variable name="random" select="java:java.util.Random.new()"/> <xsl:variable name="x" select="java:nextInt($random, $max) + 1" /> <!-- this is the random number --> <html> <head> <title/> </head> <body> <img src="{images/image[$x]/@val}" /> </body> </html> </xsl:template> </xsl:stylesheet> Here I have used the Java extension mechanism provided by Xalan.
